2017 M4 CP Cab Stage 1 Tune - BHP results inside!

Hey all,

A couple of weeks ago I got my M4 tuned with bootmod3 and stage 1 as well as a GTS transmission update, PCW exhaust mod and new rear tyres (Goodyear Eagle F1).

Man what a difference now! I posted a review of the work here.

The dyno results are in with Tesco Premium Momentum 99RON Unleaded Fuel!



535 BHP! Couldn't believe it, was expecting just 500 or something so that's made a HUGE difference! How does that compare to others having the same tune done?


Here's an image of the car actually on the dyno, it was so powerful and grippy they struggled to keep it on it through acceleration!

Think you really need the before figures to see the gains. Probs should have done a run on standard map then stage 1

Dynos do vary lots, as much as 20%. Did you get the latest GTS software update, the one that came out this month.

No it means I can't see the "updated" version mentioned above just the one you refer to
